DSPIC33CK64MP202-I/SS Descripción general
A digital signal controller combines the computational capability of a 16-bit MCU with DSP engine features such as single-cycle MAC, hardware divide, and barrel shifter. Within the power-management hierarchy, DSCs sit between general-purpose microcontrollers and dedicated DSPs, and are the standard choice for closed-loop control loops running at switching frequencies in the tens to hundreds of kilohertz.
Key features include the 12-bit, 3.5 Msps ADC with up to 15 channels for simultaneous multi-phase current sampling, 4x2 high-speed PWM channels with 2 ns edge resolution supporting complementary or independent outputs with dead-time insertion, an integrated analog comparator, a 12-bit DAC for reference generation, and a CAN Flexible Data Rate (CAN FD) module for industrial and automotive networks. Dual-partition flash with ECC enables live firmware update without external memory.
The modified Harvard architecture executes from a 3.0 V to 3.6 V supply and maintains DSP throughput of 100 MIPS across the industrial temperature range of -40C to +125C. The on-chip op amps buffer shunt-resistor signals directly, reducing BOM cost and board area in motor-drive power stages.
Typical applications include digital power supplies (LLC, totem-pole PFC), brushless DC and PMSM field-oriented motor control, LED drivers, and advanced sensing and control in industrial automation, metering, and IoT nodes.
Design consideration: all VSS and VDD pins must be connected during in-circuit programming, and PGECx/PGEDx must be used as matched pairs - mixing pairs from different channels prevents ICSP programming.

Aplicaciones típicas
DSPIC33CK64MP202-I/SS es adecuado para 6 aplicacións: Digital Power Supplies (LLC / Totem-Pole PFC), BLDC / PMSM Field-Oriented Motor Control, Automotive Body and Powertrain Auxiliary Control, LED Drivers and Smart Lighting, Industrial Sensing and IoT Nodes, Uninterruptible Power Supplies (UPS) and Inverters.
Digital Power Supplies (LLC / Totem-Pole PFC)
The DSPIC33CK64MP202-I/SS fits digital power conversion because its 2 ns PWM edge resolution gives sub-1% duty-cycle granularity at 100 kHz-plus switching frequencies, and its 12-bit ADC converts at 3.5 Msps so current and voltage samples complete before the next PWM cycle. In an LLC stage, the 4x2 PWM channels generate complementary outputs with hardware dead-time insertion, while the integrated op amp buffers the shunt-resistor current signal without an external amplifier. Placed between the rectified bus and gate-driver inputs, the DSC closes the voltage-mode or current-mode loop entirely in firmware, allowing soft-start, burst mode, and fault limiting to be retuned without hardware changes. Dual-partition ECC flash supports live firmware update so converter tuning can ship post-deployment.

BLDC / PMSM Field-Oriented Motor Control
For sensorless or encoder-based FOC, the DSPIC33CK64MP202-I/SS executes Clarke/Park transforms and the PI current loop at 100 MIPS using the single-cycle MAC DSP engine, with loop rates well above 20 kHz. The 3.5 Msps 12-bit ADC samples two phase currents via the on-chip op amp and internal comparator provides cycle-by-cycle overcurrent trip independent of the CPU. The 4x2 high-speed PWM drives a three-phase inverter through gate drivers, with the 2 ns resolution compensating dead-time distortion at low modulation indices. The CAN FD interface links the drive to a higher-level automation network. This combination eliminates external current-sense amplifiers and comparator ICs, cutting BOM cost in compact servo and e-bike drives.

Automotive Body and Powertrain Auxiliary Control
The H-grade sibling DSPIC33CK64MP202-H/SS shares this exact die and footprint with AEC-Q100 qualification to +150C, making the 28-SSOP platform suitable for automotive pump, fan, and actuator control. On the I-grade part, designs operating in-cabin at -40C to +125C benefit from the CAN FD module for gateway connectivity, the 12-bit ADC for position and temperature feedback, and the 2 ns PWM for precise solenoid current shaping. Because all four MP/MC 28-SSOP variants are pin-compatible, one PCB supports multiple trims and regions by swapping silicon and firmware only. The dual-partition flash with ECC also enables field reprogramming of calibration tables via CAN FD in service, a requirement in many automotive subsystem specifications.
Recomendado
LED Drivers and Smart Lighting
High-brightness LED drivers benefit directly from the DSPIC33CK64MP202-I/SS's 2 ns PWM resolution, which achieves smooth dimming ratios beyond 10-bit even at switching frequencies of several hundred kilohertz. The 12-bit ADC reads LED current and die temperature through the integrated op amp front end, enabling constant-current regulation with thermal foldback implemented in firmware. The 12-bit DAC provides a dynamic reference for analog dimming, letting one PWM channel handle switching while a DAC sets current level - a topology that removes noise-coupling issues common in fully PWM-dimmed designs. The dual-partition ECC flash stores multiple brightness profiles and supports live update of lighting scenes without dropping output, valuable in architectural and stage lighting products.
Recomendado
Industrial Sensing and IoT Nodes
In industrial monitoring and metering nodes, the DSPIC33CK64MP202-I/SS combines DSP-grade signal processing with practical connectivity: the 3.5 Msps 12-bit ADC oversamples sensor channels, firmware FIR/IIR filters built on the DSP engine extract measurement values from noisy transducer signals, and CAN FD or UART transports results to plant networks. The 8 KB SRAM holds buffering for burst sampling, and the integrated op amp conditions shunt or bridge signals for power metering. Operating from a simple 3.3 V rail across -40C to +125C, the part suits outdoor enclosures and switchgear environments. Dual-partition flash with ECC permits secure firmware refresh in the field, and the modified Harvard architecture keeps filter execution deterministic, which simplifies metrology accuracy validation.
Recomendado
Uninterruptible Power Supplies (UPS) and Inverters
Single-phase UPS and solar micro-inverter designs use the DSPIC33CK64MP202-I/SS to generate a sinusoidal PWM waveform with the 2 ns PWM edge resolution, producing low output THD at carrier frequencies above 20 kHz. The 3.5 Msps ADC simultaneously samples output voltage, battery current, and bus voltage each switching period, allowing firmware to implement inner current loops and outer voltage loops with anti-windup and ride-through transfer logic. The analog comparator provides hardware-level protection against shoot-through and bus faults in microseconds, independent of software latency. Live-update dual-partition flash enables grid-code compliance updates post-installation, and CAN FD coordinates parallel inverter units in higher-power rack systems.

Notas de diseño
During ICSP programming, PGECx and PGEDx must be used as matched pairs (e.g., PGEC2 with PGED2) and all VDD/VSS pins (pins 8, 15, 24, 28) must be connected - per Microchip's device documentation, a single floating supply pin will cause programming to fail even though the device runs fine in application. Reserve one programming pair as a dedicated header on every PCB; sharing PGED pins with high-current switching nodes can corrupt in-circuit flashing.
Place a 100 nF ceramic decoupling capacitor directly across each VDD/VSS pin pair (pins 15/8 and 28/24) with vias to a solid ground plane, plus 4.7-10 uF bulk capacitance near the device. The 12-bit ADC benefits from a clean 3.3 V rail - ferrite-isolate the AVDD path if a switching regulator shares the rail. Keep the OSC1/OSC2 crystal traces short and guard them with ground pour to minimize jitter on the 100 MHz PLL clock.
When driving external gate drivers from the 2 ns-resolution PWM outputs, route PWM traces away from the 3.5 Msps ADC analog inputs (pins 2-7, 13-14, 20-23) to prevent switching-edge coupling from corrupting current samples. Use the internal comparator for cycle-by-cycle overcurrent trip rather than a software ADC threshold, so fault response does not depend on CPU latency. Estimated: keep analog trace impedance below 100 ohms and series-damp PWM outputs with 22-33 ohm resistors to control ringing.
The device runs from a single 3.0 V to 3.6 V rail. Estimated: at 100 MHz with all peripherals active, core plus peripheral current is typically in the tens of milliamps (per the datasheet electrical characteristics), so a 100 mA-class LDO suffices for logic-only designs; budget extra for GPIO loading of gate-driver inputs. Ensure the 3.3 V source meets the ADC reference tolerance if VREF+ external reference is not used on pin 2.
